Abstract
Abstract In the present research, a series of hybrid nanocomposites based on polylactic acid (PLA) matrix and mixtures of graphene oxide (GO) with carbon nanotubes (CNTs) or carbon nanofibers (CNFs), at various loadings, were prepared and experimentally studied. Several experimental techniques were employed to analyze the morphology and the thermomechanical performance of the materials, as well as the dielectric properties. The related experimental data support the conclusion that a synergistic effect is exhibited by the PLA/GO/CNT nanocomposites. This effect was verified by the higher mechanical enhancement, the higher crystallinity and the development of conductive paths into the bulk matrix.
